cci small rifle primers
CCI Primers are continuously tested and improved. As a result today’s cci small rifle primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible.
Number 41 Mil-spec primers are made to the same specifications of the U.S. Military and reduce the chances of a slam-fire. While designed for you in Military-style semi-auto rifles, they use the same data as CCI magnum primers.
Note from CCI:
Effective slam-fire prevention requires more than mil-spec primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, case condition and other factors can affect slam-fire potential.

HUSEN –
These primers are obviously the safest primers to use when reloading for any bolt carrier with a free floating firing pin such as the AR and for that they deserve a solid 5 stars. If you are reloading for accuracy? They fall short compared to other small rifle primers such as CCI 400 and winchester srp. I shot several different loads through my Saber Defence AR 15 chambered in 204 Ruger with a 24″ varmit barrel 1 in 12 twist. The CCI 400 were the most accurate with my best group of .632. The CCI 41 was the worst at 2.184 at 200 yards. Bullets used were sierra 39 gr. Blitzking and H4895 powder..

HAVE LOADED ABOUT 500 ROUNDS AND AM WELL PLEASED WIH THEE PRIMERS.
LEONARD –
Reloading .556 mm rounds – works just fine – not worried about slam fires, and really wish more people carried these.
DEVARD –
Someone should take the time to package our primers better since they cost so much. The box they shipped my primers in was HUGE , 2.5’L x 9″ x 9″ The box that the primers were in was open and two of the trays were out almost completely. It would be a disaster to have to pick up spilled primers.
GARY –
These are my go to primers for AR 15 platform rifles. Very reliable.
KELVIN –
I like using the #41 primers when I reload for my semi auto rifles. They give me a little peace of mind against slam fires. The primers work well. They aren’t bench rest primers, but that’s not their purpose. In thousands of rounds I haven’t yet had a dud and I can get very consistent groups using these primers.
CIERRA –
These are a must if you’re trying to duplicate military ammunition. The cups are a little harder which is good for those of us that have military rifles with floating firing pins, and they burn a little hotter too.

I load these in; .20P, .204R, .223, 5.56, & 6.5X47 L. All these rifles have good spring tension and adequate firing pin protrusion and absolutely no fail to fire. Accuracy is equal to match primers for my use. The #41’s set off 40 grains plus of H4350 or RS Hunter in the 6.5X47L with outstanding accuracy in 30 degree temps. There appears to be less anvil protrusion on the 41’s compared with 450’s.

I like to use these primers when I am loading Military Spec 5.56 Ammo. I feel more confident relying on the experience from Billions of rounds fired using this military spec primer.
NICK –
If you are loading to military specs you should use this primer. If you are loading to .223 Rem the regular CCI small rifle primers are fine. I don’t seem to have primer flattening or other signs of primer inadequacy in my 5.56×45 loads.
NEL NELL –
Been through several thousand and not one FTF to date.
BISTY –
Interesting comparison: Using Hodgdon CFE 223 powder,same load in PMP 223 cases and LC 5.56 cases, with CCI 41 primers in the LC cases and WSR primers in the commercial cases resulted in average velocity of 75 fpm less in the LC cases. Fired in my Roger Mini 14.. My load, 27.5 gr is nearly compressed in the LC cases, but in the PMP cases powder level is somewhat lower, indicating that I could load more powder into the commercial cases. But that doesn’t explain the increased velocity. I purchased the #41 primers simply because of my intent to reload mil spec cases which are plentiful where I shoot. Since I have two more bricks left, I will use them up but am unlikely to reorder them, but switch to Winchester small rifle primers. ‘

used in both 300 AAC and 5.56 and for both it worked great, no misfires no dented primers. work the same as any other small rifle primers
JONI –
I haven’t had a dud yet they work great
ACE –
Used this for plinking and for percision loads. Have gone through thousands with zero issues. This is all I will use for simi auto 233/556.
GEOFF –
I use these for 223/556 in Mini-14 and 30 Carbine in a 1943 USGI M1. I shoot the carbine loads in my Blackhawk revolver as well. They fit, and they work. Every time. I have put thousands of my own re-loads through these guns without a failure. All milspec ammo has crimped primers and must be pocket swaged. Like other reviewers, I have encountered crimped commercial cases from Hornady, Winchester, and other brands. Your case prep must include pocket inspection and swaging if required. It’s a simple step I do right before I trim.
CANET –
My preferred primer for reloading 5.56 and 300 blackout! have not had a single primer fail out of thousands!
BURI –
Great product, adds a layer of safety when loading for the AR type rifle, and lights fine in my bolt gun as well. All around a good component.
CXEDC –
I have loaded over 3000 rounds of match .223 ammo using these primers and they have been 100 percent reliable. I only use Winchester brass and if the primer pocket is prepped properly (see what I did there?) they slide in nice and snug using an RCBS Hand Priming Tool.
CLINT –
Have not used yet. To early to really tell. But all forums have this powder and very good for the 223 calibur. Can only suggest it is awesome! Time will tell.
CASSANDRA –
Tested these primers loading for my AR rifle. Great primer!!! Slightly thicker cup to help reduce slam fires. No problems and always have fired. No misfires.
BOB JONES –
Safe choice for your AR. Tight fit, reliable & pricey but so is the ER.
ELRY –
Great product and packaging and fast shipping;will buy again!
KHAN –
Same excellent quality as other CCI primers, built to work flawlessly in the AR rifle platform. An excellent value.
AKTER –
Excellent results in both 556 and 300 blackout.
RICH –
Quality product. Never a slam fire and always fired. 500 of 1,000 down range already. I will buy more.
GOLDEN –
I was finally able to get a couple boxes of these primers for loading rounds for my AR. I have had no problems seating these primers in either commercial or mil-spec brass. Ignition has been trouble-free, and I seem to notice that my rifle is grouping somewhat better than with standard small rifle primers I was using. I like these so well, I grabbed up a box for my M1A loads. I fell better, knowing I’m taking an extra precaution against slam-fires by using these primers. I’m satisfied.
SANNY –
They go bang every time in every load I use them in.
